I saw you had a shutDown event but removed it. A setPassword event and kickAll event would achieve the same effect but allow the events to start the server up again, useful in between games when the bricks are loading or whatever.
Input events like onBricksLoaded and onBricksCleared would be great too.
I recommend you just go through the RTB server settings list and basically add events to change it all. That would be awesome.
Does the duplicator apply events using serverCmdAddEvent? If not, you have a potential risk with this.
Edit: Ooooh. Could you add parameters for loadSaveFile for the load offset? With VCE support?
